  • I had the opportunity to work with Phage Consultants on a project that my company had in Bazancourt, France. The project consisted in the manufacturing of bio-based succinic acid using an E.coli production system. With the help of Phage Consultants, we conduced an audit of the production facility to identify potential issues related to bacteriphage contamination, and from that audit we developed a phage prevention plan. Phage Consultants did a remarkable job and we were able to prevent phage contamination. They are very professional, efficient and most importantly trustworthy. I highly recommend them for any problems related to phage contamination

  • I have personally worked in 2016 with Marcin Los and his company Phage Consultants in solving phage contamination issue in one of our service provider's facility. His actions and the help provided by company helped our contractor to get rid of recurrent contamination and to restore production according to Marcin's recommendations. Since then, our service provider was able to deliver product of interest in a reliable manner and the problem did not re-occurred. I can recommend co-operation with Marcin and his company Phage Consultants, as they showed to be very effective and professional in solving phage outbreak problem and in providing a long-term prevention solutions.
